Thomas Weißschuh 3ebb1b6522 sched: Fix preemption string of preempt_dynamic_none
Zero is a valid value for "preempt_dynamic_mode", namely
"preempt_dynamic_none".

Fix the off-by-one in preempt_model_str(), so that "preempty_dynamic_none"
is correctly formatted as PREEMPT(none) instead of PREEMPT(undef).

Fixes: 8bdc5daaa0 ("sched: Add a generic function to return the preemption string")
